Whois lookup response gives error when calling its properties method

Question

Using this gem: whois (3.6.5)

Doing this:

Whois::Client.new(timeout: 2).lookup('miaz.ca')

And then trying to call .properties on the result of the call (pasted below)

"Domain name:           miaz.ca\nDomain status:         registered\nCreation date:         2014/03/12\nExpiry date:          

2018/03/12\nUpdated date: 2017/03/02\nDNSSEC:

But then calling Whois::Client.new(timeout: 2).lookup('childrenandco.qa') gives this response and .properties gives a undefined method 'zip' for "shops.myshopify.com":String:
